Abstract

Samples from a new generation of metal particle tapes have been analysed by Mossbauer spectroscopy and magnetic measurements. The Mössbauer results show the presence of both metallic α-Fe(Co) fine particles and a very important fraction of iron oxide. An out-of-plane distribution of the Fe spins within a mean angle of around 26° has been evidenced by Mössbauer spectroscopy, in acceptable agreement with the magnetic data. The spin dispersion seems to be related especially to dynamical effects.
